PowerDesigner comes with 2 Editions (DataArchitect and EnterpriseArchitect) and is available with different licensing models (simplified since version 16.6). Some of them were deprecated by SAP, others are still valid. This may create some confusion as to which edition, type of license and capacity is the right fit for a given project.

After a day of struggling with trying to simulate an LM2678 based buck converter (see: this post) another user suggested using TIs online power designer web bench tool to simulate. Selecting a design on the site gave me just about the exact same circuit I had designed by hand for a 5v buck converter using the design equations found in the LM2678 datasheet. I'm struggling to make sense of the simulation results from TIs web-bench, in fact they seem entirely nonsensical to me:
Could someone explain to me what this means, if anything? I'm expecting to see a constant 5v out of the steady state analysis voltage over the load but maybe I'm just not understanding what the results are telling me?
The waveform that you're seeing labeled transient response shows how the output voltage fluctuates due to a changing demand in current downstream from the converter. This can tell you a few things such as: stability, overshoot / undershoot, response time, and more.
When the red waveform (load current) goes from 3A towards 0A, the energy that was stored in the inductor L1 doesn't change instantaneously, and therefore must be absorbed into the output capacitor Cout. This results in a voltage increase in the voltage output. The opposite change in load current causes the voltage at the output to drop since the power converter cannot respond as quickly as the load is being demanded. The energy is temporarily supplied by Cout and causes a dip.
Usually you want to know how the output responds under rapid load changes of different frequencies so you can determine if your output voltage is stable and within the max/min voltage of the downstream parts that power is supplied to.

There are already wireless power charging devices available across the market, but one notable company has been absent from the craze. In a very uncharacteristic move, Apple has discontinued development on its AirPower device for wireless charging.
Wireless power transfer, sometimes abbreviated as WPT, has been an area of interest for electrical engineers since the days of Tesla, who dreamed of wireless power distribution across long distances. While that dream has never been fully realized, there has been intense interest in the area of wireless charging for years, from familiar industry names such as TDK to less expected names such as Disney Research, which aimed to create a room to allow wireless charging via quasistatic cavity resonance.
As the astute reader will quickly grasp, electromagnetic induction is akin to a transformer and is the principle employed in the Qi standard. The obvious problem is that the lack of the common magnetic core of an actual transformer lowers efficiency. Additionally, distance and poor orientation between the transmission and receiving coil exacerbates the problem.
Magnetic resonance-based wireless power transfer transmits power involves deploying series capacitors in both the power transmission and receiving sides to form LC resonance circuits. By tuning both sides to resonate at the same resonance frequency, the system can keep consistent power, even if there are coil misalignments or bigger distances between coils.
Of course, the entire issue can be avoided with chargers defined for only one product. This is the method employed by devices such as electric toothbrushes, where the device fits into its charger in a mechanically determined manner, assuring that the transmission and receiving coils are aligned perfectly.
To get around the coil-alignment issue, Apple seems to have aimed to equip the charging device with multiple transmission coils. In this manner, one or more of them would be likely to align properly with the device under charge.
As a power engineer, it seems to me that the moral of the story, demonstrated time and time again by non-specialist tech companies but never fully absorbed, is that power design requires dedicated specialist organizations and cannot be approached as a mere side project.
GaN Systems, for their part, has announced an evaluation system, the GSWP050W-EVBPA, which is designed to help designers more quickly incorporate its GS61004B E-HEMT power amplifier, a 50-watt device, into magnetic resonant power transfer products.
Tri-Power Design, LLC develops and delivers powerful innovative engineering solutions, which enable companies to better manage the process of bringing products and processes from the drawing board to the marketplace.
As the world races towards net-zero emissions, high-efficiency electric power conversion is becoming increasingly important. The trend calls for cutting-edge power electronics designs based on the latest semiconductor materials and topologies. This creates a significant challenge, since the traditional approaches to power converter design cannot keep up with the pace of innovation, the growing complexity and exponential growth in the number of design solutions.
